UPDATE #2 (5/22): Welcome Pen Addict readers! And, for those of you who arrived at this post some other way, make sure to check out Pen Addict's "Ink Links" post published today and every Saturday, where you'll find lost of links and likely discover (like I do) a new blog or two you want to follow nearly every week.
UPDATE #3 (5/22): Just this week, I learned that Brian Goulet of Goulet Pen Co. (and the teriffic Ink Nouveau vlog) is also offering samples. For now, he's only offering J. Herbin and Pelikan inks, but he's got some colors in those brands that Pear Tree pens didn't offer samples of the last time I ordered, and you don't have to order in sets of 4 . . . so I ordered 11 more samples from Brian yesterday!
